9 Claims. (Cl. 155-62) This invention relates to swings and particularlyto devices of this character intended for use on lawns and in playgrounds.

Theobject of the invention is the provision of '5 a-sw ing which will hold one ormorep'ersons, which will be .simple and strong in construction and which may vbesafely used by very small children.

This object is attained by the mechanism :illustrat'ed in the accompanying drawings.

10 For the purpose of illustrating .the invention,

the appended claims.

Figure 10 represents a plan of one .of the spring caps.

Similar characters indicate like parts throughout theseveral figures-of the drawings.

m the drawings, 10 is a pipe forming .a part .of the usual "supports used in public playgrounds.

= -Depending from this support 10 are two 'sepa-,

rated hangers 11 formed in twopartsiand clamped together by bolts 12. i

To insure against movement onthesupport 11), the hangers 1 1 have set screws 13, :the inner ends 1 of which impinge upon the periphery .of the support 10 and'lock the hangers :in position.

Between the hangers 11 is disposed .a tubular member 14 having a downward extension .15' in "which'is a socket 1-6 to receive-the upper end-ofza 5.5 wooden bar '17.

This bar is secured in position in the socket 16 by means of bolts 18 having thumb nuts .19 threaded thereto, as shown :in Figs. 5 and 6 of the drawings. v

Secured to the under face of ears 20 forming '60 part of the hangers 11 are cross plates 21.

Through each cross plate and midway between the hangers 11 is a bolt 22 having a head 23 at its lowest end and a nut 24 threaded to the opposite end.

Between" the under face of the plate 21 and the head 23, the bolt 22 is surrounded by a helical spring '25, the opposite ends of which are positioned in annular washers 26, as shown in Fig. 9 of the drawings, said-washers being secured to the spring 25 by means of ears 263: shown 'inF-ig. 10.

The extension 15 of the member 14 isprovided on opposite faces with bosses 27, which during the movement. of the member 14 contacts with the heads 23 of the. bolts 22 and limit the movement of the members '14, 15 about theaxisof its pivotal connection with .the hangers 1 1.

This pivotal connection consists of a cylindrical member 28within'the tubular member 14.

The opposite ends of member 28 are reduced in diameter as at 29 and these reduced ends are surrounded by annular collars 30 having peripheral grooves .to receive a plurality of anti-friction members 31, said members 31 extending into grooves in "the annular members32 at the opposite ends of said tubular member 14.

"The member 28 has oppositely extending threaded shanks 33 which project through holes in the hangers 1'1 and haveolamping nuts 34 securedto. the outer ends thereof.

These nuts 34 may be turned sufiiciently to :clamp :the hangers 11 against the outer faces of the reducedends 29 0f the member 28 so that said member .28 cannot rotate about its axis.

Between the. inner cylindrical face of the tubularzmember 14, and the periphery of the member: 28, :thereis'a' chamber 35 which is filled with lubricant, this-lubricant being introduced into c'saidzchamber by removing the threadedplug 36 in the upper-end of member 14. V

@Wll'lglifl the anti-friction members surround- ;ing the reduced ends 29 and .the lubricant intro- .duce'dintoithe'chamber 35 surrounding themem- :ber :28, ".the member 14 will freely oscillate about theaxisof the member28,.and alldeviation from the vertical :plane is entirely prevented.

The lower end of the bar 17 has a metal strap 37 secured thereto at-38with its opposite ends39 bentldownwardly-to forma triangle and said ends 1310 39 are secured to the opposite faces of the bar 17 at 48.

Secured to the upper face of the horizontal portion of this strap 3'? are two oppositely disposed seats 41 preferably of saddle shape, as shown in Fig. 3 of the drawings.

Secured to opposite faces of the bar 1'? at a point above the seats 41 are elongated handles 42, the vertical portions of which are surrounded by resilient closures 43.

These resilient closures 43 ailord a yielding grip for the occupants of the swing and the vertical portions of these handles are of sufiicient length to be seized by either a small or large child.

The bar 17 also has secured to opposite faces of its extreme lower end metal plates 44 to which are secured oppositely disposed U-shaped stirrups 45 by bolts 46.

These stirrups 45 are formed in such a manner as to give upper and lower footrests to accommodate children of different sizes.

The vertical portions of these stirrups 45 are surrounded by resilient closures 47 as a safety precaution to prevent injury to children in case they get in the path of the swing and are hit thereby.

It will be noted that the swing will always move in the same vertical plane and there is no possible chance for deviation therefrom owing to the construction of the pivotal connection with the fixed hangers 11.

By providing the shock absorbers 25 the movement of the swing in either direction is limited and when either of the bosses 27 come into contact with the bolts 22, 23, the springs 25 will yield and gradually stop further movement in that direction.

At the end of the playground season it is desirable to store the lower part of the swing for the winter months and install it again in the spring.

This can easily be accomplished by removing the bolts 18 and then removing the bar from the socket 16.

This swing is very strong, may be easily in-, stalled, and is safe for use by even very small children.

It is believed that the operation and many ad vantages of the invention will be understood without further description.
